CARL L. GROHMANN AND IRA C. KOEHNE, OF DAYTON, OHIO, ASSIGNORS TO THE NA- TIONAL CASH REGISTER COMPANY, OF DAYTON, OHIO, A CORPORATION OF OHIO,

(INCORPORATED IN 1906.)

CHECK CASH-REGISTER.

Application filed December 3, 1906.

T0 all whom t may concern Be it known that we CARL L. GROHMANN and IRA C. KOEHNE, citizens of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Check Cash-Registers, of which we declare the following to be a full, clear, and exact description.

This invention relates to cash registers and has among its objects to provide a check or coin displayer serving to retain on eXhibition the checks or cash received during several operations of the machine.

A further object is to provide an improved check or coin conveying mechanism whereby the check or coin deposited may be moved gradually past a sight opening and iinally deposited in the machine.

Another object is to provide a check or coin displayer connected to a cash register of an ordinary type so that the operation of the cash register may serve if desired to actuate the check displayer and that the operation of the check displayer may in turn if desired actnate the cash register.

Vith these and incidental objects in view the invention consists in certain novel features of construction and combination of parts, the esential elements of which are Set forth in appended claims and a preferred form of embodiment of which is hereinafter described with reference to the drawings which accompany and form part of this specification.

Cf said drawings: Figure 1 is a vertical transverse section through a well known type of cash register to which our invention may be applied, this view showing only a few parts of the register. Fig. 2 is a transverse vertical section through the check displaying mechanism.

The invention is shown as applied to a cash register of the type patented to Thomas Carney No. 532,7 62, J an. 22, 95, but it will be understood that this is merely by way of illustration and the check displayer may be used with many other types of register. For a full description of the cash register reference may be made to the above patent but it may be generally stated that the register is provided with a series of value keys 10 and special keys 11 all journaled loosely on a main rod 12 and each provided at the Specification of Letters Patent.

rear end with a projection 13 on which rest indicator standards 14 for each key. The standards 14 have tablets 15 mounted thereon and are raised to bring the tablets 15 into indicating position. A key coupler 16 is mounted on trunnions 17 in the main frame of the machine, a rear extension 18 of said coupler serving to pass into notches 19 of the amount and special keys thereby compelling the keys to move together. The

the depending end of the pawl 21 rear-- wardly enough to engage the frame standard 22. As the special keys 11 have some movement before the key coupler is encountered it is necessary to provide some means for returning the said keys with the coupler and to this end is pivoted on each special key 11 as indicated at 24 a pawl 25 having a projection 26. When the special key 11 and amount key 10 are operated the coupler rises with the two keys and the rear extension 18 thereof gradually enters the notches 19 of both keys. This relative rearward movement of the coupler serves to rock the pawl 25 around its pivot 24 finally carrying the projection 26 under a hook 27 of the pawl 21 when the spring 23 immediately passes the hook 27 over the projection 26 thereby latching the pawl 25 so that it projects directly under the key coupler eXten- The mechanism as thus far described is found in the machine as now on the market and is not part of the present invention. This invention is comprised in the cheek displayer shown in Fig. 2 andmay now be described.

It was previously stated that the key coupler 16 was mounted on trunnions 17 journaled in the main frame of the machine. One of these trunnions 17 is extended and on the outer end thereof is rigidly fastened a depending arm 31 having a notch 32 cut in the bottom thereof. Riding in this notch vis a tooth 33 of a bell crank arm 34 journaled on a pin which is mounted on an arm 36 loose on the trunnion 17 of the key coupler. It may be here noted that Fig. 2 is drawn from the opposite side to that from which Fig. 1 is drawn so that a counter clockwise motion of the coupler as viewed in F ig. 1 will produce a clockwise motion of the arm 31 as viewed in Fig. 2. The bell crank 34C is provided at the rearward end with a flange 35 normally in front of a locking block 361. W' hen the amount key 10 is slightly operated as is the case in the type of machine shown, the coupler is raised slightly and arm 31 is therefore thrown rearwardlyT rocking bell crank 311 around its pivot 35a and depressing flange 35 below the lug 36:L and below a locking notch 37 of a locking arm 38 also journaled loosely on the coupler trunnion 17. vrlthis arm 38 carries a pin 39 on which is'loosely mounted an arm 10 normally drawn by a spring Lt1 connecting a pin 42 on the said arm to a pin 13 on arm 36. It will be clear that when bell crank 34 is rocked as above stated and flange 35 thereof depressed that the locking notch 37 of arm 38 will move over the flange under the impulse of spring 41 and retain the said flange and the attached mechanism in the adjusted position. A. bar 51 is provided riding on an antifriction roller 52 at its rearward end and at its forward end is bifurcated to form racks and 54 meshing successively with a gear 55. The bar 36 has mounted thereon a pin 56 carrying an antifriction roller 57, the said roller passing through a slot 58 in arm 31 and a slot 59 in bar 51. It will be seen from the shape of the slot 58 that the described motion of the arm 31 may take place without moving the roller 57 or its carrying bar 36, the purpose of which is to rock the flange 35 out of the path of the locking lug 36;L so as to enable the rocking of bar 36 when the forward end of the slot 58 in arm 31 contacts with the pin 56 projecting from said bar. By this means the handle 95a, as hereinafter described, is locked from operation until the coupler 16 has been partly moved. When however the key 10 is given its complete operative stroke the arm 31 is moved farther rearward and by reason of the forward end of the slot 58 contacting with the rolle-r 57 will move the bar 36 carrying said roller rearward .and through the roller 57 and slot 58 moves the bar 51 also rearward. At this time the flange 35 rides along the under side of locking lug 36a carrying with it also the arm 38 and arm 40 mounted thereon. This arm 410 rides along the top of the lug 36a as it is provided with a flange 62 which when the arm 40 is slightly depressed strikes the top of the said lug 36". Before the key 10 completes its movement to raise the key coupler the flange 62 passes ofer the real ward end of the lug 36 and then moves downwardly. lllhen the keys of the register return to normal position the arm 31 moves forwardly carrying the flange 35 forward under the locking lug36, but during this motion the flange 62 strikes the rear edge of lug 36a and is held there, thereby stopping the motion of arm 38 which has previously moved with the flange 35. Further movement of arm 31 carries flange 35 away from the locking notch 37 of the arm 38 and said flange finally passes free of the locking lug 36?' when it rises to the position shown in Fig. 2. lt was stated that during this operation the flange 62 remained against the rear edge of the locking lug 36l and it will be clear that the upward movement of flange 35 will rock the arm 40 around its pivot at 39 thereby carrying the flange 62 above the lug 361. Then this happens the spring 41 will draw the arms 38 and l() forwardly returning them to the position shown in this figure.

It was stated that racks 53 and 54 mesh successively with a gear 55. This gear is fast to a roller 71 around which is fastened a conveying belt 72 having a number of cleats 73 spaced around the same at equal distances. At the rear end the conveying belt passes around the roller 74 journaled in the main frame. (ln the rod 75 carrying the gear and the attached mechanism is journaled an arm 76 normally urged to rotate to the right by a spring 77 connecting one end of said arm to the main frame. Rollers 78 and 79 are provided on racks 53 and 54 and these rollers are adapted to engage and rock the arm 76 to tension its spring 77. Attached to the bar 51 is a projection 82 having a flange 83 beveled as shown. On the frame of the machine is a second similarly beveled lug 84 adapted to cooperate with the lug 83. rllhe purpose of these two lugs and the arm 76 is to insure that the reciprocation of the bar 51 will produce a continued rotation of gear and thereforea continued forward movement of the conveying` belt.

F ig. 2 shows the parts in normal position and it will be remembered that an operation comprises a movement of arm 31 toward the leftof the figure and then a reverse movement thereof. When arm 31 is so izo moved toward the left the forward edge of slot 58 will soon abut the antifriction roller 57 and the further movement of arm 31 will carry the roller 57 and bar 51 rearwardly. The rack 53 is now in mesh with the gear 55, a counter clockwise movement of the said gear is produced, and at the same time roller 78 engages the rear end of arm 76 and gradually rocks the same against the tension of spring 77. Meanwhile camming lug 33 is moved under camming lug 84, and finally passes free of the rearward end of the same. When this occurs the spring 77 may contract, rocking the arm 76 and therefore through the antifricton roller 78 raising the bar 51 at the forward end thereof. This bar is raised enough to carry the rack 5 4 into mesh with gear 55 and arm 31 then moves back to its normal position carrying the bar 51 with it. During this return movement of bar 51 the beveled lug 83 rides over lug 34 and the antifriction roller 79 finally engages and rocks arm 76 again tensioning spring 77. At the end of the forward stroke of bar 51 the lug S3 passes free of lug 84 and it andthe bar 51 are immediately depressed by spring 77 This operation takes' place at each actuation of the device and clearly serves to give the conveying belt 72 a forward motion twice at each operation. The extent of movement is arranged to be just sulhcient to place a succeeding cleat 7 3 in the previous posit-ion of the preceding cleats so that at the end of any operation the cleats as a whole occupy precisely the same position.

Directly over the conveying belt is a piece of transparent material 92 through which the checks or money on the belt may be observed. The inserted articles are deposited through the cut away portion 93 of the displayer frame and allowed to drop on a table 94 having corrugations 95 on the top thereof. A frame comprising pivoted arms 94EL connected by a rod 95ZL is journaled on a main rod 96 and is connected through a link 97 with the arm 36. Depending from the handle rod 95a is a frame including a bar 9S having depressions complementary to the corrugations 95. It will be remembered that antifriction roller 57 mounted on arm 36 passes into the slot 59 of bar 51 and therel by compels the said arm to move rearwardly at each operation of the machine in correspondence with the movement of bar 51. This mechanism clearly provides that the frame bar 98 will be swung over the corrugations 95 of the table 94 and will serve to push any articles deposited on said table before it and finally allow them to drop on the conveying belt 72. When the frame rod 98 reaches the rearward limit of its travel to deposit the inserted articles on the belt the cleat 73 indicated by 7 3X is directly abutting the rear end of table 94 thereby preventing the coins from dropping ofll of the conveying belt. As the mechanismy is returned to normal position the cleat 7 3X finally reaches the position shown in the figure as occupied by the preceding cleat and it will be clear that in this posit-ion of the mechanism a withdrawal of the inserted articles is not possible, since a belt guard 7 3y attached at opposite ends of the main frame holds the belt and its cleats 73 so close to the transparent material as to preclude their withdrawal through any crevice. Depending rigidly from the rear edge of said table 94 is an arc-shaped sheet of metal 94X compelling the displaying as aforesaid of articles which otherwise might be thrown over the rear edge of table 94 and downward into the drawer.

The mechanism has been described as if all the power was furnished by theregister keys the displayer handle serving as a mere pushing device for the inserted articles. It will be observed however that the whole operation may take place by the manual moving rearward of the handle bar 95a, which will, through link 97, rock the arm 36 just as it was rocked by the complete operation of the key. It is of course necessary in this scheme of operation to slightly depress the amount key 10 to move the flange 35 from in front of the locking lug 36a but when this is done the slightly operated key 10 is attached to the key coupler 16 and the further movement of said coupler through the handle rod 95a and the connecting mechanism will serve to completely operate the register key.

The displayer is provided with a cash safe having a movable part which is released by the operation of the value keys. This cash safe is shown in the present case and it will be understood that it is in the base of the displayer and is to be ejected when desired. A lateral flange is provided on the forward end of this drawer and this engages a latch 121 pivot-ed on a pin 122 and adapted when the drawer moves outwardly to a very slight extent only to drop over the pin 123 connecting the link 97 to the arm 94a. This mechanism clearly serves to lock the displayer if the cash drawer is out of normal posit-ion. When the cash drawer is pushed completely in the flange referred to strikes the lower end of latch 121 raising the hook end of the same away from pin 123 so that the displayer may again be operated.

As the conveyer belt is moved intermittently at succeeding operations the inserted articles are gradually brought to the rear thereof and finally pass over the roller 74 dropping into a receptacle 126 from which they may be taken at any desired time and in any desired manner.

As previously described, the partial operation of any of the keys 10 will withdraw the ange 35 of the bell crank 34E out of the path of the locking lug 36a, thereby permitting the operation of the handle 95a by the operator in connection With the key so as to assist said key in the operation of the machine. This conjoint operation of the key 10 and the handle 9521 prevents any torsional strain of the parts that might occur if either the key or handle were operated alone.

It Will be seen that the register keys comprise a primary driving mechanism for the conveying belt and the hand lever mechanism and parts connected thereto form a supplementary driving means for the same. A locking means for the supplementary driving means is found in the bell crank 84: and attached parts, this locking means being actuated by the primary driving means. This mechanism is of use in many other relations besides that indicated in the drawings and it isdesired to claim it Without reference to the particular function performed in this case and Without reference to the particular mechanism employed to perform the said function. The arched detent 38 provides a second locking means which is released by the arm 40 pivoted thereto, this arm- .LO serving to hold the locking means previously referred to in its unlocking position. This mechanism is also of use in other relations besides that in Which it is shown.
